Compozer (Sand compaction pile method)

The composer method uses a vibrating hollow pipe for repeated driving and lifting to create large-diameter, well compacted sand piles in soft ground for ground stabilization. It is the most representative of the sand compaction pile methods and is the most widely used. This method was developed and commercialized by this company as a world-wide first. It has been implemented in all parts of the world and the total length of all installed piles exceeds 380,000 km.
